DOOR-LATCH.

Specification of Letters Patent. Pat td D 1917.

' Application filed July 21. 1917. Serial No. 181,995.

and State of \Yisconsin, have invented certain new and useful improvements in Doorllatrhrs. of which the followup, is a spemlr cation.

This llll'klltlOll relates to door latches and artii'ularly to lair-hes For sectional doors,

sum-h; for example. as the [lo n-disclosed in application Serialho. 182.0%. hled July 31, 1917. by \Villianr l1. Kissel and John llCd- (rick \Vern'er".

The objm-l of the invention 1:510 provide a latch for each section of the (l()0)', S;llLl latches being operable by means of a single handle: and the connection between the latches being of suchcharacter that the door sections may be readily connected and. disronnorted. l

la the accompanying drawings, Figure 1 is an inner side view of a door provided with a latching mechanism embodying the features of my invention. Fig. 2 is an enlarged .l'ragnwntal view of the latch for the upper.

door scrlion. Fig. 3 is a sectional view taken in the plane of dotted line 3--3 of lwg. 2. Fig. 4 is a fragmcntal view showing the latch for the upper door sectlon and the keeper therefor. Fig. 5 is a detail View of mgnide' for the actuating connection beform a-lower section and an upper. section,

tween the latches. I d

In Fig.1, I have shown. a door for an antolnobile body similar to the one fully d15- closed in .said Kissel & Werner application. Herein the joining line of the door sections Each section 1s provided with a latch. The latch S for the lower door section may be of any suitable or well-known construction and, therefore,

I. have deemed it unnecessary toillustrate said latch in dc'tail. The bolt 4 is arranged to he slid by means of a handle 5. Upon the bolt 4 is a cam surface 6 against which rests the lower end of a rod]. This rod extends through a guide opening 8'(F1g. 5)

in the latch casing and through a groove 9- in the upper door-section. The upper end of the'rod is attached to a slide '10 which is inclosed within a casing 11 secured to the upper door section. A'pin 12 extends slidably into an opening 13 in the slide. A coiled spring 14 interposed between the head of said pin anda shoulder 15- on the slide 10 tends to more said slide and, the rod? downwardly: l'pon the slide is a projection 16 adapted to lie at one side of a keeper 17 secured to the door frame. The adjacent ends of the j'iroieriion l6 and the keeper 17 0 are rounded at one side to cause the projection 16 to be forced upwardly as the door is closed. As soon as the ,Pl'OjOCtlOI'l 16 has passed the keeper. the coiled spring l-l'move's the slide downwardly to place the projection 16 behind the keeper 1?, as shown in Fig. 4. As fully explained in said Kisselv & Werner application, the door-sections l and 2 are separated from each other'by sliding the upper door-section toward the right as viewedin Fig. 1. This may be done without bending the rod 7, as the groove 9 in' which said rod lies is wide enough to allow for the necessary relative movement between the door-sections. The door-sections may then be moved apart, the rodr'l' being Withdrawn from its guidecopening 8. When desired, the door sections may be united by a reversal of the bperations just described.

It will be seen that when the bolt l is moved inwardly to release the lower doora latch for the lower section including a bolt, a spring normally holding said bolt in operative position, a lever for movin the bolt out of operative position against t e action of said spring, said bolt having a camsur'-. face on its rear portion, a latch on the upper section normally held in operative position, and an actuating rod carried by the upper: section with its lower end bearing. on said cam surface, said roId being movable by said cam surface when the bolt is moved outof operative position to move the latch forthe upper section out of operative position.

2. A vehicle dolor transversely divided to formalowcr section and an upper section, a latch for the lower section includin a mem-fg ber movable transverselyof the oor and 9 having its forward end normally held in on eratire position, a latch 'for the upper sec"- tion including a member movable longitudinally of the door and having a projection normally held in operative position, and arod operatively connected to said latch members and adapted to be moved by the transversely movable member to move the projection on said longitudinally movable memher out of o' erative osition, said rod bein disconnect-e from but movable by saic transversely movable member.

3. A vehicle door transversely divided to form a lower section and an upper section, latches for said sections each having a member normally protruding from the same edge of the door, one of said latch members being movable transversely and the other longitudinally of thedoor, and a member operatively connected with said latches and arranged to be moved longitudinally of the door by one latch as it is moved out of latching position, to move the other latch out of latchin position, said latch-moving member being t isconnected from the latch by which it is moved 4. A vehicle door having two latches, each having a member normally protruding from the same edge of the door, one of said latch members being movable transversely and the other longitudinally of the door, and an operating connection between said latches for transmitting movement from one to the other.

5. In combination with a vehicle door having a lower section and an upper section relatlvely movable on said lower section for disengagement therefrom, a latch upon each of said'sccti ns, and a rod extending between said latches for transmitting motion from one latch. to the other, said rod being disconnected from the latch by which it is moved, and there being a. guide opening for the rod in one section and a groove for the rod in the other section, said rod being laterall v movable relatively to one of the door sections to permit relative movementbetween said door sections.

6. In combination with a vehicle door having a lower section and an upper section relatively movable on said lower section for disengagement therefrom, a latch upon each of said sections, and a rod extending be tween said latches for transmitting motion from the lower latch to the upper latch, said rod being disengageable from the lower latch, and there being a groove in the upper door section in which said rod is movable laterally to permit relative movement between said door sections.

In testimony whereof, I have hereunto set my hand.

JOSEPH ARTHUR TARKINGTON.
